Application of Addressed Fiber Bragg Structures for Measuring Tire Deformation

Abstract

The article discusses a possibility of using fiber-optic sensors based on address fiber Bragg structures (AFBS) to assess a dynamic of tire. A motivation for a study is to develop an economically sound sensor system for measuring forces acting on a wheel. A description of multisensory measurements technology of continuous monitoring of the tire state was presented and disscused. Information from the sensors is used as input parameters of algorithms that allow evaluating key characteristics, such as longitudinal and lateral friction forces. One of the advantages of this new technology is the fact that an optical photodetector is used as microwave photonic interrogator, which greatly simplifies the system.
